Constructor Detail

DefaultTableModel

public DefaultTableModel(int rows_,
                         int columns_)

Constructs a DefaultTableModel with the specified number of rows and columns, and with cell values of null.

DefaultTableModel

public DefaultTableModel(java.lang.Object[][] data_,
                         java.lang.Object[] columnNames_)

Constructs a DefaultTableModel and initialises the table by passing data_ and columnNames_ to the setDataVector method.

Method Detail

getColumnCount

public int getColumnCount()

Get the number of columns in the model.

getColumnName

public java.lang.String getColumnName(int column_)

Get the name of the specified column.

Specified by:

getColumnName in interface TableModel

Overrides:

getColumnName in class AbstractTableModel

getColumnWidth

public int getColumnWidth(int column_)

Get the width of the specified column.

getRowCount

public int getRowCount()

Get the number of rows in the model.

Specified by:

getRowCount in interface TableModel

Specified by:

getRowCount in class AbstractTableModel

getValueAt

public java.lang.Object getValueAt(int rowIndex_,
                                   int columnIndex_)

Returns an attribute value for the cell at (rowIndex, columnIndex)

setValueAt

public void setValueAt(java.lang.Object value_,
                       int row_,
                       int column_)

Sets the attribute value for the cell at position (row, column).

Specified by:

setValueAt in interface TableModel

Overrides:

setValueAt in class AbstractTableModel

setDataVector

public void setDataVector(java.lang.Object[][] data_,
                          java.lang.Object[] columnNames_)

Replaces the values in the _dataVector instance variable with the values in the data_ array. The first index is the row index, the second index is the column index. The columnNames_ array supplies the new column names.

setDataVector

public void setDataVector(int rows_,
                          int columns_)

Set up an empty data vector with the specified number of rows and columns.
